Spotlight has this built in and I use it quite often: If I enter a name it shows the contact details like phone, mail etc. and I'm able to copy that data. It would be awesome if the launcher would show contact details upon entering a name and even better if there was a hotkey or click to copy button that allows to easily copy that information.
good idea, I have added contact search in 6.647. Will be on alpha update in 30min
